Alberta’s ongoing oil slump has forced WestJet Airlines Ltd. to cancel nearly a dozen daily flights out of the province’s two largest airports, primarily to western energy hubs.

The Calgary-based carrier announced its summer schedule Monday, which will see six fewer daily flights from Calgary’s international airport and five fewer from Edmonton.

WestJet’s Richard Bartrem said the changes, slated to take effect March 5, are a reflection of the changing needs of passengers in a province mired in a massive slump in oil prices, and primarily impacts flights to energy hubs.
